The Solar Arc Direction
Precise work requires not only the coordination of a number of degrees with
years of life but also calculation of the individual solar arc. The solar arc for a particu-
lar year of life denotes the distance between the solar position on the day of birth and
the number of days that corresponds to the year of life in question.
This is also expressible in a formula:
Birthday
+ Days as years of life
_____________________________
= Index day
Solar position on index day- Solar position on birthday
= Solar arc
Example: Male born June 20, 1971
- 21 days
= June 41
In June there are
- 30 days
= July 11, 1971 = index day.
The Sun is at 28°55’ Gemini on June 20, 1971.
The Sun is at –19°01’ Cancer on July 11, 1971.
18°54’ = solar arc for 26 days
We now have to calculate the progressed positions to the planets by adding the
solar arc of 18°54’ to each planet. In order to differentiate the positions of the natal
chart and the progressed positions, the natal chart is on the insideof the 90° wheel and
planets are marked in black. The progressed positions are on the outsideof the 90°
wheel and marked in red (or any other color), thus making the relationships between
the progressed cosmogram and the natal figure recognizable. Those configurations
that immediately hit the eye are usually the most significant ones.
It is very important to consider the points lying opposite as well, because
these constitute the semisquares and sesquiquadrates. In times past, these aspects
were often ignored, because they are difficult to determine. However, statistics show
that these aspects are at least equal in importance to the others. In the cosmogram
they are easy to spot.
TransitsThe word transit means going over, and in cosmobiology, it refers to one planet’s pas-
sage over another. Stellar bodies in the cosmogram are considered primarily to be
